@jeyson-app/jeyson-api-mcp

An MCP (Model Context Protocol) server that connects AI coding assistants — Cursor, Claude Desktop, VS Code Copilot, Windsurf — directly to your Jeyson API workspace. Your AI assistant can list your schemas, call them live, and generate ready-to-paste integration code for any mobile or web platform.

Tools

| Tool | Description | |---|---| | jeyson_list_schemas | Lists all schemas in your app with field definitions, endpoint URLs, auth requirements, and token balance | | jeyson_call_schema | Calls a schema endpoint live and returns the structured JSON response | | jeyson_get_integration_snippet | Generates platform-specific integration code for a schema |

Supported platforms for jeyson_get_integration_snippet: swift · kotlin · flutter · react_native · javascript

Setup

1. Find your credentials

Go to your Jeyson Dashboard → Settings → copy your App ID and API Key.

2. Configure your AI tool

VS Code (GitHub Copilot)

Create .vscode/mcp.json in your project root:

{
  "servers": {
    "jeyson": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@jeyson-app/jeyson-api-mcp"],
      "env": {
        "JEYSON_APP_ID": "YOUR_APP_ID",
        "JEYSON_API_KEY": "YOUR_API_KEY",
        "JEYSON_BASE_URL": "https://your-jeyson-domain.com"
      }
    }
  }
}

Cursor

Create or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "jeyson": {
      "command": "npx",
      "args": ["-y", "@jeyson-app/jeyson-api-mcp"],
      "env": {
        "JEYSON_APP_ID": "YOUR_APP_ID",
        "JEYSON_API_KEY": "YOUR_API_KEY",
        "JEYSON_BASE_URL": "https://your-jeyson-domain.com"
      }
    }
  }
}

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "jeyson": {
      "command": "npx",
      "args": ["-y", "@jeyson-app/jeyson-api-mcp"],
      "env": {
        "JEYSON_APP_ID": "YOUR_APP_ID",
        "JEYSON_API_KEY": "YOUR_API_KEY",
        "JEYSON_BASE_URL": "https://your-jeyson-domain.com"
      }
    }
  }
}

Usage examples

Once connected, you can prompt your AI assistant:

What schemas do I have in my Jeyson app?

Call the sentiment_analysis schema with the prompt "I love this product"

Generate a Flutter integration for my meal_tracker schema

Add the sentiment_analysis schema to my Swift ViewController
